Hi everyone
For sale is my Ashdown CTM-100 which I purchased new from Ashdown in the second half of 2025. I was interested in trying a tube amp as part of my bass rig to help me get a nicer low end, and always loved the Trace Elliot gear I used so decided to try one of Ashdown's amps for the job, settling on the CTM-100.

I bought the amp, and a loadbox (I play without cabs) and played around with the CTM-100 at home and was quite pleased with the sound I could get out of it, but after a few weeks (only one rehearsal with my band and one gig) I decided that it was a bit overkill, to use a piece of kit like this for the job I needed, which was just a clean low end in conjunction with several other amps doing various other jobs. Having to carry around a big heavy amp head, and a loadbox, and then barely using it to it's full potential ended up being a more impractical arrangement than I had first imagined.

Initially, I had contacted Ashdown to see if I could swap the CTM-100 for something smaller, and less powerful, since the amp is basically in 'as new' condition, having only been taken out to a gig once, and despite coming to an agreement, that swap never happened and it is a year now since that conversation took place, so I have decided to sell it instead. It is in pretty much perfect condition, and has been living in its original box/packaging for the past year or so.

I had initially planned to do a CTM-100 custom order, where I would go and try some different things with the guys at Ashdown, but that also never really materialized, and although this amp was sold as a CTM-100 Custom build (and charged for that price too!) it is effectively just a regular CTM-100 with one of the Tube's being different from the regular builds, as far as I am aware. I have very little knowledge about Tubes etc though, so can't really give more information than that. I can say that my amp sounds the same to me as the other CTM-100 (and the CTM-200) that I tried.

If you are looking for a Tube bass amp head, then maybe this is perfect for you. I paid £1300 for it, and given that it is still pretty much unused, hopefully the asking price is reasonable and can save someone a few hundred quid who doesn't mind going second hand.

Thanks for your interest, and feel free to ask any questions you might have! I will do my best to answer
Pickup is preferred for an item like this, but I am also happy to drop off within a reasonable distance from SW London.
